3 Claims. (01. 136-180) (Granted under the act ofMarch 3, 1883, as

amended April 30, 1928; 3'70 0. G. 757) This invention relates to a battery filling and ventilation unit.

In the use of batteries on submarines or in any closed compartment, the ventilation of storage cells is a problem. 'After aperiod of use and the placing of a charge in said battery,

it is found that duct lines, covers and individual cell leads become saturated with acid. During the charge, as the gassing point is reached, the gas forming in the electrolyte forms minute bubbles, the film being electrolyte These bubbles are carried along with the ventilating air into the ducts. This naturally causes rapid corrosion, requires constant cleaning and can lead,

todangerous battery system grounds and to thebattery liquid, thereby'reducing the vapor to its original state and returning the liquid to the battery cell.

Further objects and advantages of this invention, as well as its construction, arrangement and operation will be apparent from the following description and claims in connection with the accompanying drawing, in which Fig. 1 is a sectional elevation of the filling and .2- baflles l8, I9, 20, and 2| (see also Figs. 3, 4,5, and 6). As shown in Figs. 4 and 6, baiiies l9 and 2| have arcuate slots concentric the peripheries or said baflles. The centering ring I! and v baiiies l8, I9, 20, and 21 are positioned and secured by' use of spacers 22 and locknut 23 applied to suitable threading on the filling tube In. Spaced within the flange 26 of the baflle l6 are a series of drip openings 24.

Protruding from the side of the barrel l I is an exhaust channel 25 to complete the path of circulation.

A preferred material for parts Ill-23 and 25 is hard rubber.

, In operation, the battery filling and ventilation unit acts as a mixing bowl. The difference in temperature between the air insidethe battery and the outside air sets up a circulation. The colder outside air is drawn down the filling tube It. The warmer inside air rises through the openings 21 in the centering rin II. This warmer air carries with it the vapor and the globules formed from the electrolyte. Then the series of baflles causes a turbulence or mixing action resulting in the collision of the vapor globules, reducing them to their original state so that the electrolyte returns to the cell by way of the openings 21, and the gas is drawn 011 through exhaust channel 25.

This eliminates the accumulation of water and electrolyte in the ventilation duct lines.

Various modifications and changes can be made in the subject device without departing from the scope of the invention.

The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties Filling tube I0 is held in position with reference to the barrel II by use of an externally and internally threaded collar l2. Barrel cap I3 is secured in any suitable manner.

The barrel II is secured to the top of the battery M by any suitable means such as the doubly threaded collar I5. A cylindrical baflie l6, preferably in the shape of two similar frusta of a cone disposed oppositely to definean hourglass configuration, has a flanged portion extending outwardly from the nether end thereof abutting the interior wall of the barrel I I. Said baflle I6 is welded to and positioned by a centering ring 11 (see also Fig.2). Above the centering ring II are placed a series of bafiles, in this case four thereon or therefor.

We claim. I I

'1. In combination a, storage battery and a battery filling and ventilating unit comprising an opening within the top of the battery, a raised cover and a barrel fitted over said opening, a

filling tube disposed vertically within and passing through the top of the barrel, a perforated centering ring circumscribing the filling tube, a ,bafile supported by said ring on said tube interior said barrel, said baflle being shaped similarly to an hour glass and centered about the filling tube at the restricted portion by the centerin ring and having a nether flanged portion, a series of circular baflles with staggered openings spaced above the restricted portion of the baflie and surrounding the filling tube, a series of drip open- 3 ings in said flanged portion of said bafle, and an exhaust channel passing through an upper portion of the side of the barrel.

2. A storage-battery filling and ventilating unit comprising a, barrel adapted to be mounted over an opening in the top of a battery, 9. filling tube secured in and extending through said barrel, a perforated centerin ring circumscribing said filling tube within said barrel, a cylinder having a constricted medial portion mounted on the periphery of said centering ring and having a nether perforate flanged portion abutting the interior wall of said barrel, a. plurality of annular baflles having staggered openings mounted in spaced relation on said tube interior said cylinder, and an exhaust conduit communicating with the upper portion of the side of said barrel.

3. A storage-battery filling and ventilating unit comprisin a barrel adapted to be mounted over an opening in the top of a battery, a filling tube secured in and extending through said barrel, a perforated centering ring circumscribing said REFERENCES CITED The following references are of record in the file of this patent:
